Seems like the problem is that it invokes the following superclass constructor which does not initialize things properly (note the null values):

protected FileState(Descriptor descriptor) {
this(descriptor, null, null); // HACK: subclass don’t use these
}


Should this constructor disappear?
I tried invoking FileState’s ‘proper’ constructor and then things work fine.

I don’t think that’s where this problem comes from. If you look at getAnalyzedAST() you can notice that it doesn’t actually use those fields. The EditorState class gets the parse controller from the editor.

I see. But getAnalyzedAST() also calls getResource() which isn’t overridden and therefore returns null.

Would you suggest overriding this method as well? For example:

@Override
public IResource getResource() {
    return getParseController().getResource();
}
